I installed new wiring and the new LED rear lights on my trailer last night. Got everything working except for one little problem.
The trailer brake lights work.
The trailer turn signals work.
The trailer hazards work.
The one thing that DOES NOT WORK are the running lights, ie the lights that are dimmer than the brakes/turn signals but are on all the time when the lights to the car are on.
I followed the wiring instructions to the book so don't know what could be causing this problem. Unless someone can enlighten me, I'll probably buy a set of standard trailer lights and see if it's the light itself. That's my only guess.
TO ADD: I searched some more trailer posts. The wiring harness is new. The rear LED "submersable" lights are less than a year old and did previously work when connected to the truck (2003 Chevy Trailblazer). The wiring harness was chewed up and some lights did not work at times so we decided to replace the whole wiring harness, ie fish it through the trailer and back.
The connections were done via the twist caps, and then wrapped with electrical tape where the new wires met the wires on the LED lights.
The (Trailer) ground was done on the same bolt as we have always grounded it. We loosen one of the 4 bolts that attaches the hand crank wheel to the trailer, wrap it good, then tighten the bolt back up.
The connection from the trailer is a 3 female and 1 male connection. It connects to an adapter with LED test lights built in. Then the adapter connects to the rear of the Trailblazer. The adapter has female recepticles and the Truck has the male ones.
Would I need to look to see if the truck's harness is grounded? I would imagine it is if it's getting brake and turn signal lights to the rear.
I'll mess with it again tonight when I get home but really don't have any ideas of what else to check as every connection and the wires are new.
Could I have possibly wired the LED lights and the trailer wires backwards?
I'm at a loss.
